AB-QM 4.0 / AB-QM Pressure Independent Control Valves (PICV) DN 15-250

The AB‑QM valve equipped with an actuator is a control valve with full authority and an automatic balancing func tion / flow limitation. Typical applications are: Temperature control with permanent automatic balancing on terminal units (chillers, air‑handling units, fan coils, induction units, radiation panels and heat exchangers). Without an actuator is a flow limiter e.g for one‑pipe systems.

Description

The Danfoss AB-QM is a Pressure Independent Control Valve (PICV) that combines high accuracy and durability with market leading user-friendliness. The design of the AB-QM is fully geared towards making your project run on time and on budget while delivering the most efficient HVAC system. Pressure independent valves are control valves with an automatic balancing function. An in-built pressure controller keeps a constant differential pressure over the control valve, ensuring full authority and automatic flow limitation. By combining two functions in one, control and automatic hydronic balance, Danfoss PICVs provide a cost-efficient solution for the challenges faced by forward-looking designers of HVAC systems.

The Danfoss AB-QM delivers the lowest total cost of ownership because:

• Precise flow limitation ensures always the right flow at the right time, ensuring minimized pumping energy

• Full range from DN15 to DN250 for flows up to 407 m3/h

• Available with internal and external thread for universal applicability

• Danfoss’ durability test ensures the AB-QM has best-in-class resistance to scaling and clogging

• Easy troubleshooting because of the always visible setting and the ability to measure flow through test plugs

• Minimum hysteresis for stable and precise temperature control

• Future-ready with a range of smart actuators, ready for data driven and optimized HVAC 4.0

NovoCon® L

NovoCon® L is a high accuracy multi-functional fieldbus actuator, specifically designed for use in combination with the Pressure Independent Control Valve type AB-QM in sizes from DN 125-150 used in air handling units AHU, chillers and distribution station applications. NovoCon® L SU/SD has a builtin a spring that will close the valve (Spring Down, SD) or open the valve (Spring Up, SU) if the power on the actuator is lost.

Presetting

DN 15‑32

The calculated flow can be adjusted easily without using special tools. The change of presetting (factory setting is 100% (10) follow steps below:

1. Remove the blue protective cap or the mounted actuator

2. Raise the pointer (DN 25-32)

DN 15 ‑ 32

DN 15, 20

0 - 10

DN 40 ‑ 100

3. Turn the pointer (clockwise to decrease) to the

new setting

4. Press pointer back into lock position (DN 25-32) the presetting scale indicates

values from 100% flow to 0% (DN 25-32) and 10-0 (DN 15-20). Clockwise turning would decrease the flow value while counter clock wise would increase it.

Service DN 15‑32

For the service shut off function, it is recommended to install the valve in the supply water pipe.

DN 40‑10 0

For the service shut-off function, the valve can be installed in either supply or return pipe.

Valves are equipped with manual shut-off for isolating function up to 16 bar.

Tender text

A pressure independent balancing and control valve with a linear control characteristic that is independent of the available pressure and setting. Make: Danfoss AB-QM or equivalent.

The pressure independent valve should have the following features:

• Automatic flow limitation function

• Membrane driven design for reduced clogging risk

• Modulating below 1% of set flow, regardless of the setting

• Maximum flow clearly marked on the valve

• Authority of 1 at all settings

• Ability to close against 16 Bar of differential pressure.

• Linear control characteristic

• Linear setting

• Control ratio 1:1000

• Test plugs for pump optimization and flow verification for DN 15-250. Available in the range from DN 10 – 250 from one supplier.

• Option to change the characteristic from linear to equal percentage at all sizes by adjusting actuator settings.

• Leakage rate of no visible leakage (IEC 60534-4:2007 class IV) for DN 15 - DN 20 in combination with recommended actuator

• Leakage of 0.05 % of the Q recommended actuator

• Leakage of 0.01 % of the Q recommended actuator

• Flow measurements (AB-QM DN 15, 20) according to BS7350:1990

DN 125‑250

For the service shut-off function, the valve can be installed in either supply or return pipe.

For shut-off set the valve to 0%.
